Difficult cold start

I think I will convert to pointless electric ignition. I have seen guides here how to use hei parts.
But I found this in ebay:
for MOPAR Slant Six Hi-Po Electronic Ignition Kit OEM Dart Duster 225 170 198 | eBay

Have anybody used this? Is it crap or useful? It should fit without modifications.

Can anybody suggest mini starter that would fit to -64 valiant with 170 slant from rockauto?
It looks that there is many options available.
